And he'll be the first to remind you that working as a plumber the day after Thanksgiving is a dirty job, but, as he says, "Somebody's got to do it. As long as you pay me, I'll do it. It doesn't matter to me."

Historically, the day after Thanksgiving is the busiest day of the year for plumbers. And it's not because of the secret between Uncle Mike and the porcelain throne. Instead it has everything to do with the kitchen sink.

"Green bean casserole, sweet potatoes, mash, they just jumble it in and the garbage disposal clumpsit in and that's what happens every single time," Naveda said.

And according to him, it's about the grossest thing you can find.

"Everything, once it gets into your drains, it turns into this mush. It's just a black funky mush, and it kind of smells like a perm, if you've ever smelled that before," he said.

"It gets on you and it gets in your nose so all day long no matter what you smell," he added.

Interestingly enough, plumbers say that every time they get the call, it almost always has something to do with in-laws.

"A lot of mother in laws is what I'm told. Father in laws, they stick a lot of stuff down the garbage disposal," Naveda said.

And the cost to fix the problem isn't cheap. It starts off at about $90 and goes up from there. So think about that the next time you finish your Thanksgiving meal and run off to the stores. What's that called again?

Naveda knows. "It's Black Friday. I don't know what it means to other people, but I know what it means to me."
